Part Number: TPS63070

Hi team,

About the enable control, is there any restriction about retring the device by EN signal? (EN : ON -> OFF -> ON)

Hi Saito,

There are no restrictions. Do you only want to use EN to turn the device on and off?

Hi Saito,

We haven’t heard back so we're assuming this answers your question. If not, just post a reply below, or create a new thread if the thread has locked due to time-out.

Thanks and regards,

Hi Milos-san,

Thanks. It's clear now. They just want to use EN to turn on and off the device. Competitor's custom device has some EN on/off timing restriction.

So, they just concerned if this device also has such a restriction.

Regards,

Saito

Hi Saito,

There is a start-up delay time from EN = High until the device starts switching, which is typically 70 μs. If you have a specific sequence for the EN pin that needs to be tested, please let us know and we can check it.

Best regards,
Milos
